· JVASP-131453· LuAu3

LuAu3 is an intermetallic compound combining lutetium and gold in a 1:3 ratio, belonging to the family of rare-earth–noble-metal intermetallics. This material is primarily of research and academic interest rather than established industrial production, with potential applications in high-temperature structural materials, catalysis, and advanced electronics where the combination of rare-earth and precious-metal properties offers unique phase stability and electronic characteristics.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
